I was learning from a video resource and ran into this error when told to hit Ctrl-F5 in the View in order to load it directly. By doing this, I ran into the same error message you posted.

As Kevin answered. I was changing the project name and namespacing in my MVC project. When I ran the application I got the same error "Line 1: <% .....".

I use FTP to upload DLLs of my site on the server but sometimes this error happen when the main DLL of the website has not been uploaded correctly on the server.

So I recommend you to rebuild you project and re-upload main DLLs on the server again.
